I have three drives that have a lot of overlap. If I setup the union mount as a "FF" (or just use the default) it will get the file from the first mount point it finds. My question is suppose that mount point returns an error for some reason (quota, or whatever). Is it possible to have it try the next mount point?
For example suppose
Union of Mount 1 and Mount 2 with FF.
If I try to read A it would read from Mount 1. But suppose Mount 1 gives a quote error. Is it possible to fail to try to read from Mount 2 instead of just ... dying?
